Which expressions are equivalent to 71-x-3)? Select two options.
0-53x-21
-7-x-7(3)
763x-21
6*x-4
4
71-x)+7(3)

Answer:

20

Step-by-step explanation:

f(x)=x2+3x and g(x)=2x2, find (f ∘ g)(−1)

f(x)= (-1)(2) +3 (-1)= -2+-3= -5

g(x)= 2 (-1)2= -4

(f ∘ g)= -5 x -4= 20

Step-by-step explanation:

[tex]y = \frac{1}{2} e^{x}[/tex]  equation is represented by the given graph.

"Graph is defined as the representation of relation between two variables on the coordinate plane."

According to the question,

From the observation of the graph,

for x= 0

y- intercept = [tex]\frac{1}{2}[/tex]

a.  [tex]y = \frac{1}{8} e^{x}[/tex]

Substitute x = 0 in the equation we get,

[tex]y = \frac{1}{8} e^{0}[/tex]  

⇒ [tex]y = \frac{1}{8}[/tex]

Therefore,

Option (a) is not the correct answer.

b. [tex]y = \frac{1}{2} e^{x}[/tex]

Substitute x = 0  in the equation we get,

[tex]y = \frac{1}{2} e^{0}[/tex]  

⇒ [tex]y = \frac{1}{2}[/tex]

which is same as graph value.

Hence, Option (b) is  the correct answer.

Answer:

it's the first one

Step-by-step explanation:

since all of them go up to 8 on the graph it

the graph represents it going down since the first one is the only one to go down that one represents the graph precisely.

Answer:

V = 7385.28

Step-by-step explanation:

Formula of the volume of a cylinder: V = pi*r^2*h

Since you are told to replace pi with 3.14, now plug in the numbers that you are given into the formula...

V = (3.14)(14)^2*(12)

= 7385.28

Notes: Remember you always have to divide your radius in half if it gives you a diameter, BUT since in this question it's given, you don't have to do any extra work :)

Given:

The two points are C(3,-5) and D(7,9).

To find:

The midpoint M of the given points.

Solution:

We know that,

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

Using the midpoint formula, the midpoint of C(3,-5) and D(7,9) is

[tex]M=\left(\dfrac{3+7}{2},\dfrac{-5+9}{2}\right)[/tex]

[tex]M=\left(\dfrac{10}{2},\dfrac{4}{2}\right)[/tex]

[tex]M=\left(5,2\right)[/tex]

Therefore, the midpoint M of two points C(3,-5) and D(7,9) is (5,2).

Answer:

M + 11.7

Answer:

m+11.7

Step-by-step explanation:

Answer:

646

Step-by-step explanation:

To solve this, you would need to know the volume of a sphere and volume of a cube.

Volume of a cube is L x W x H

8x8x8 which gives you 512

The volume of a sphere is [tex]\frac{4}{3} \pi (r)x^{3}[/tex]

(radius which is 8/2=4)  4/3 pi (4)^3=268.08

Because this is half a sphere, simply divide the volume by 2 and you should get 134.04.

512+134.04=646.04

=646 cm cubed

Answer:

6y + 48

Step-by-step explanation:

Use distributive property 6 x y = 6y

(keep the plus sign btw)

6 x 8 = 48

then place it in order: 6y + 48 is your algebra expression

Answer:

6y + 48

Step-by-step explanation:

Distributive Property

6 * y = 6y + 8

A = 29.745

you can use the law of sine

Answer: 84 degrees

Step-by-step explanation: I'm not quite sure how to explain this problem, sadly, but you basically add up the degrees together in the big triangle all together, and then figure out the rest.

Answer:

y = -4x + -3

Step-by-step explanation:

We know the slope-intercept form is y = mx + b, and m is the slope of the line, and b is the y-intercept. To find the slope, we need to divide the difference of the y coordinates by the difference of the x coordinates. We already have the slope listed there which is very helpful, so now all we need to do is find the y-intercept (where the line goes through the y axis). If we count the lines on the y axis starting from the origin and going downwards, we see that the line passes through at (0,-3), so the y-intercept is -3. Now we replace the variables with the correct numbers, and the answer would be y = -4x + -3. I hope this helped!! :]

x = -2

Step-by-step explanation:

4(x+5)=12

Distribute.

4x+20=12

Subtract 20 from both sides.

4x+20-20=12-20

4x = -8

Divide both sides by 4.

4x/4 = -8/4
